When I worked at Zebra Systems, we used to make the Spectrum Light Pens for
Bob Rosen which were simply a photo detector mounted into a magic marker
I can't find anything on Rainbow with a programming example. So I can't say
if the pen was attached to a button or the x/y axis for reading.
It was amazingly simple, and I must have built over 100 of them.
